“37. Evidence gathered through a recent survey on open access (OA) shows that, for over 80 per cent of outputs in the scope of the policy, either the outputs met the REF policy requirements in the first year (1 April 2016 to 1 April 2017), or an exception to the policy requirement is known to have applied. This reflects significant progress toward the policy intent to increase substantially the proportion of research that is made available open access in the UK.
38. The funding bodies have carefully considered the evidence gathered in the survey relating to the policy’s deposit requirements. We wish to continue building on the progress achieved to date and to maintain the momentum towards developing new tools to implement deposit as soon after the point of acceptance as possible. We therefore confirm the implementation of the REF OA policy as previously set out. The policy will require outputs to be deposited as soon after the point of acceptance as possible, and no later than three months after this date (as given in the acceptance letter or email from the publication to the author) from 1 April 2018.
39. Taking account of some of the practical concerns raised through the survey in relation to deposit on acceptance, we will introduce a deposit exception in to the policy from 1 April 2018. This exception will allow outputs unable to meet this deposit timescale, to remain compliant if they are deposited up to three months after the date of publication. The exception will read: ‘The output was not deposited within three months of acceptance date, but was deposited within three months of the earliest date of publication.’ This exception will remain in place for the rest of the REF 2021 publication period.
40. Further detail on the evidence assessed to make this decision is based at Annex B. The REF OA policy has been updated to include the additional exception. A full report of the UKwide survey on the delivery of funders’ open access policies will be published early in 2018….”
